IT36361: PCOM: 14.0.1 (64-BIT) BIDI FILE TRANSFER CRASH

IBM Personal Communications 14.0.4

APAR status

• Closed as program error.

Error description

• The user upgraded from PCOMM v12.0 going to PCOMM v14.0.1
  (64bit).
  
  PCOMM 14.0.1 (64-bit) is crashing "some times" when
  they do a file transfer action. The user is running in Hebrew
  locale (BiDi).
  
  They had few crashes in one day due to
  receiving a file from their host going to a PC.
  
  If the file
  contains only few lines, it works without any problems and the
  Hebrew letters are shown fine.
  
  But once the file gets bigger,
  it crashes and the Hebrew letters are showing garbage (or
  distorted characters).

  ****************************************************************
  PCOMM is crashing due to the buffer overflow while performing
  the 3270 IND$FILE file transfer.
  The copy buffer API used in 64-bit does not ensure the
  prevention of the buffer overflow.
  

Problem conclusion

• PCSXFER.DLL has been changed to use a Secured version of copy
  buffer API to fix the problem.
